Define species, variation, and correlation. Then, using a photo of dogs, identify similarities and differences, explain what these differences are called, and why dogs are the same species. Finally, e

Explain the meaning of the following words:

• a) A species is a group of organisms that can naturally interbreed and produce fertile offspring.
• b) Variation refers to the differences in characteristics or traits among individuals within the same species.
• c) Correlation describes a relationship or connection between two or more things, where a change in one tends to be associated with a change in the other.

Look at the photograph of different kinds of dogs.

• a) Identify three similarities between the dogs.

  • All have tails.
• b) Identify three differences between the dogs.
  • Differences in size.
  • Differences in fur color and pattern.
  • Differences in ear shape.
• c) What are these differences known as?
  • These differences are known as variation.
• d) Explain why dogs are said to belong to the same species.
  • Dogs are said to belong to the same species because they can interbreed with each other and produce fertile offspring.

Write a paragraph to explain why children look like their parents but are not identical to their parents. Children look like their parents because they inherit genetic material (DNA) from both parents, which determines their physical traits. However, they are not identical because they receive a unique combination of genes from each parent, not an exact copy of either. Genetic recombination during the formation of gametes further shuffles these genes, creating a unique genetic makeup for each offspring.
